Factors to be considered while designing a PID controller

[radhika]

Hi ,

I am designing a PID controller for a temperature control system.

What are the factors should i consider to decide the PID controller range?

I have to adjust the heater voltage to keep the process temperature under control.

How to simulate the program without actually getting the process temperature??

Will the PID Controller work with any relation (for simulation purposes)between heater voltage and process temperature??

Am not an expert in PID controller.............

could someone guide me ...........

Thanks,

radhika

Hi Radhika,

For guidelines on setting parameters of your PID controller, you can search and find good information in books and all over the web (e.g. root locus and Bode plots).

As far as LabVIEW is concerned, you might want to take a look at the Control Design Toolkit, and its manual, available here.:

And you could use something like a simulate signal express VI to simulate an input to your system.

Hope that helps! Take care,
